Application led December 24. 1918. Serial No. 26S-.140.

Massachusetts, have invented an Improvement in AutomaticFilling-Replenisliing Looms, of which the following description, inconnection with the accompanying drawing, is a specification, likecharacters on the drawing representing like parts.

' This invention relates to -automatic filling replenishing looms inwhich when-the filling needs to be replenished a fresh filling carrieris transferred from a hopper or supply mounted above the lay to the layand the spent filling carrier is ejected through a slot in the lay. Theinvention is particularly applicable to looms of the well knownNorlthrop type in which the filling carrier is a bobbin `and in whichwhen replenishment takes place the bobbin is transferred from the hopperto the shuttle on the lay,4 the fresh bobbin ejecting the spent bobbinfrom the shuttle and through the slot in the lay.

In this lgeneral type of loom the slot' in the lay through which theejected filling `carrier passes is the slot in which the picker stickoscillates. To guide the ejected filling carrier into a suitablereceptacle the cutaway or slotted part of the lay is usually providedwith an inclined chute having a part thereof upwardly extending beyondthe inner end of the path of the picker stick and'some means' isprovided to prevent the ejected filling carrier from entering the slotbetween the extended portion of the chute and the picker stick becauseif this happens the picker stick .would Vjam on its next inward strokecausing more or less damage. In the patent to Janelle No. 951,949granted March 15, 1910, a guard pivotally mounted on the lay isprovided. This guard normally covers the slotl and is swung out ofposition at each inward movement. ofthc picker stick by the picker stickcomlng into contact therewith and camming it into open position.

The present invention prov1des a movable guard for the slot between theextended portion of the chute and the picker stick which is normallymaintained in open position so that the picker stick may reciprocatefreely in the slot without contacting with the guard and the inventionalso provides for causing the guard to be moved into closed position toguide the ejected filling carrier whenever filling replenishment iscalled'for by the operation of the loom or whenever the filling `carrieris ejected. Preferably the invention also has for its object to providefor the operation of the movable guard into closed or guiding positionby or through the action Aof the transyferring'mechanism of thev loom.

The Vinvention also has for its object to provide means in connectionwith the movable guard for catching and retaining the trailing end fromtheejected filling carrier and this means preferably consists of aserrated upper edge upon the movable guard. If this trailing filling endbe not caught and held it .is likely to be carried back by the shuttleand thrown or woven into the shed causing an imperfection while if it becaught and retained it will reave out through the eye of the shuttle asthe shuttle is picked across the loom.

These and other objects of the invention will appear more fully from theaccompanying description and drawings and will be particularly pointedout in the appended claims.

The drawings show so much of an automatic filling replenishing loom ofthe Northrop type as is necessary to a disclosure of the inventiontogether with a preferred form of the invention lembodied therein.

The general construction of a loom of this type is so Well known andfamiliar to those skilled in the art that only a v ery generaldescription of those parts directly concerned with the present inventionis necessary'.

A rotary hopper 11 containing the supply of fresh filling carriers 12 ismounted by the hopper stand 13 upon the top of the breast beam 14 so asto extend above the lay. The fresh filling carriers are dischargedsuccessively as required from the hopper by a transferrer 15 pivotedupon the hopper stand at 1.6 and provided lwith a depending arm 17having pivotally mounted thereon at its lower end a dog carrier 18 inwhich is adjusta-bly mounted by means of the set screw 19 a transfer dog20.

The lay 21 beats back andl forth beneath the hopper andcarries on itsupper face the shuttle box 22 which receives the shuttle 23 at the endof the pick. The shuttle box and the lay therebeneath are verticallyslotted at 25 first to permit the movement ofthe picker stick 26 andsecond to provide for the passage of the spent filling carrier whenejected from the lay or in the case of a bobbin from the shuttle on thelay.

A transferrer bunter 27 is secured to and projects rearwardly from 'theface of th lay opposite the dog 20. i

In this type of loom when the filling on lthe running filling carrierhas reached a predetermined degree of exhaustion or has been exhaustedsuitable indicating mechanism is set in motion calling for replenish-vment and in the type illustrated this mechanism acts to swing the dogcarrier 1.8 about its pivot and raise the vtransferrer dog 20 into thepath of the bunter 27 'so that as the lay beats up the bunter 27contacting with the dog 20 will effect the actuation of the transferrerand cause a fresh filling carrier to be discharged from the hopper intothe shuttle on the lay then therebeneath and to eject the exhausted orspentl filling carrier from the shuttle downl through the slot oropening in the lay.

In order to guide the'ejected filling carrier into a suitablereceptaclel such as is usually placed on the transferrer end of tne loomthe slotted end ofthe lay is provided with an inclined chute shownA asametal plate 28 carried by a bracket 29 bolted in place at 30 to the lay.This chute extends upwardly beyond the inner. end of the path of thepicker stick and at its upper edge contacts with the rearward wall ofthe slot Y or opening 25 in the lay. It is obvious that quently, whenthe picker stick is at the outer end of its reciprocation the slot oropening in the chute between the picker stick and the edge 31 is leftopen and unprotected and the filling carrier when ejected is likely tofall into this slot and to be caught between the picker stick and thechute upon the next pick which results in injury of the loom andbreakage of the parts.

In order to protect this open portion of the chute a movableguard isprovided. This guard is shown as a plate 32 pivoted or journaled at itslower edge on a shaft 33 mounted in the chute 28 and its bracket 29.This plate is adapted when swung into its rearward or closed position tolie substantially in the same plane as the upper portion of the chute 28and with its upperedge resting against the rear Wall of the slot 25.This plate when swung into its forward-or open position standssubstantially vertically and out of the way of the reciprocation of thepicker stick so as to leave the slot 25 free for the movement of thepicker stick.

The guard is normally held in-its open position and is moved into itsclosed position for controlling the movement ofthe guard to subservethese ends is illustrated. An actuator shaft 34 is journaled on thefront face of the lay above the guard and for that purpose is shown asjournaled in ybrackets 35 projecting from the shuttle-box. This shaft 34at its outer end is provided with'a depending arm 36 connected by a link37 to the, upper end of a bracket 38 rigidly secured to the guard 32. Asplit head 39 is clamped on the shaft 34 and arm 36 by the bolt 40 andthis head is provided with a flat face 41. A bracket 42 is bolted to theface of the lay by bolts 43 and carries at its inner end a socket 44 inwhich is mounted a plunger 45 having a head 46. A helical spring 47surrounds the plunger in the socket 44 bearing against the bottom of thesocket and the `bottom ofthe head and thus acts normally to project' theplunger upwardly.v The upper surface 48 of the plunger head is flat andis so posi` angular position that the'guard 32 will be he d in its openposition as shown in Fig. j

7. Consequently any movement of the guard away from this position willbe resisted by 'the spring pressed plungerwhich thus acts at all timesnormally to restore the guard to its open position.l The depend ing arm36 is also arranged when the guard is in open position to contact with astop 49 projecting laterally from the socket portion 44 of the bracket42. j v

The actuator shaft 34 at its inner 'end is provided with a depending-arm50 to form a guard bunter so arranged that if this' bunter be struck theshaft 34 will be rocked to swing the guard rearwardly to its closedposition. Any suitable means may be used for thus moving the actuatorshaft 34 when the guard is required to be in closed position but as apreferred means a dog is `provided on the transferrer.

The dog carrier 18 is shown as prolonged downwardly at 51 and in rthisprolongation' is mounted a guard dog 52 of generally sjmilarconstruction to the usual transferrer dog 20. This dog is longitudinallyadjustable inthe carrier by means of the set screw 53 in the usualmanner. The face 54 of the dog 52 is preferably con caved. The parts areso adjusted and arranged that upon the call for filling replenishmentwhen the dog carrier 18 is swung to raise the transferrer dog 2O intothe path of the bunter 27 the guard dog 52 will be raised intoI the pathof the guard bunter 50.,r

But thc guard dog 52 is adjusted so as to; to be engaged by the bunter50 before the:- bunter 27 engages the transferrer dog 20 andconsequently as the lay beats up after the call for fillingreplenishment the guard 32 will be swung into closed position beforevthe bunter 27 engages the dog 2O and effects the transfer of a freshfilling carrier and the consequent ejection of the spent fillingcarrier. This .movement of the bunter 50 to rock the shaft 34 and swingthe guard v into closed position is indicated in its final vejectedfilling carrier being caught where it will vbe jammed by thepicker stick upon the. next pick. f

As the lay beats back after replenishment has taken place the bunter 50swings away from the dog 52 vand the spring pressed plunger 45 at onceacts to restore the guard to open position immediately allowing freepassage for the reciprocation of the picker stick.

If as is usual in connection with automatic filling replenishing loomswhere replenishment takes place prior to complete exhaustion of therunning filling and the filling still remains upon the filling carrierafter its ejection the trailing end will eX- Atend from the ejectedfilling carrier up through the slot 25 in the lay to the'shuttle and outthrough the eye of the shuttle toward the fell of the cloth'to a pointwhere it has been severed. If this trailing end is not removed from theshuttle it is likely on the next pick of the shuttle to be caught andcarried or thrown back into the shed and woven into the cloth causing animperfecti0n.- In the present invention this is prevented by providingmeanson the guard 32 catching and retaining the trailing filling end andthis means is preferably constituted as a serrated edge 55 formed at theupper edge of the guard. Immediately vafter the spent filling carrierhas been ejected the lay swings rearwardly and consequently the guardswings to open position bringing the serrated edge directly across thepath of the trailing filling end so that as the shuttle is picked acrossthe loom this trailing filling end is caught by the serrations and heldand j drawn out through the eye of the shuttle.
